The maps provide details specific to this park in a user-friendly visual format and may be viewed and downloaded from http://www.marineparks.sa.gov.au. 12/11/2010 12/11/2010 Sir Joseph Banks Group Marine Park Located in lower western Spencer Gulf and covering 2,627km2, the Sir Joseph Banks Group Marine Park includes parts of the Eyre and Spencer Gulf Bioregions. The park is adjacent to Tumby Bay, and includes the islands of the Sir Joseph Banks Group and Dangerous Reef. This marine park overlays two other protected areas, including the Tumby Island Conservation Park and the Sir Joseph Banks Group Conservation Park. 12/11/2010 1 ENVIRONMENTAL VALUES 1.1 Ecosystem services Ecosystems provide many critically important services that people benefit from, often at no direct cost to us. Examples of ecosystem services provided by coastal and marine habitats are shown in the following table. It is important to ensure that ecosystem health and integrity are maintained so that ecosystems continue to provide these services to us all. Table adapted from McLeod, K and Leslie, H (2009).

Habitats, species and natural processes found here are summarised below. 1.2 Physical influences Physical influences shape the type of habitats and species found in an area. Physical influences typical of this region include: • a transition from the cooler, oceanic waters of the Lower Eyre Peninsula to the warmer, semi-sheltered waters of Spencer Gulf; • northward flowing current entering the Gulf through the marine park, which is deflected at the head of the Gulf, creating a southward, saline counter current on the opposing shore; • dodge tides, which have a major effect on water movement in the area. 1.3 Habitat variety Table 1 Benthic (subtidal) habitats found in the Sir Joseph Banks Group Marine Park Benthic Habitat** Area (km2)* % of park Bare sand 145 5% Dense seagrass 102 4% Medium seagrass 26 1% Sparse seagrass 282 11% Granite reef 57 2% Heavy limestone reef 1 <1% Low profile platform reef 25 1% Unmapped 1979 76% * habitat areas have been rounded to the nearest whole number **habitats included are those found from mapping at a resolution of 1:100,000 Table 2 Shoreline (intertidal) habitats found in the Sir Joseph Banks Group Marine Park Length in % of park Shoreline Habitat park (km)* length Bedrock platform 5 11% Coarse sandy beach 37 79% Mangrove 5 10% Saltmarsh <1 0% * habitat lengths have been rounded to the nearest whole number Tumby Bay is a Wetland of National Importance and includes important habitats for various fish, crustacean and bird species.

    AUSTRALIAN JOINT COPYING PROJECT HYDROGRAPHIC DEPARTMENT Charts, 1769-1824 Reel M406 Hydrographic Department Ministry of Defence Taunton, Somerset TA1 2DN National Library of Australia State Library of New South Wales Copied: 1987 1 HISTORICAL NOTE The Hydrographical Office of the Admiralty was created by an Order-in-Council of 12 August 1795 which stated that it would be responsible for ‘the care of such charts, as are now in the office, or may hereafter be deposited’ and for ‘collecting and compiling all information requisite for improving Navigation, for the guidance of the commanders of His Majesty’s ships’. Alexander Dalrymple, who had been Hydrographer to the East India Company since 1799, was appointed the first Hydrographer. In 1797 the Hydrographer’s staff comprised an assistant, a draughtsman, three engravers and a printer. It remained a small office for much of the nineteenth century. Nevertheless, under Captain Thomas Hurd, who succeeded Dalrymple as Hydrographer in 1808, a regular series of marine charts were produced and in 1814 the first surveying vessels were commissioned. The first Catalogue of Admiralty Charts appeared in 1825. In 1817 the Australian-born navigator Phillip Parker King was supplied with instruments by the Hydrographic Department which he used on his surveying voyages on the Mermaid and the Bathurst. Archives of the Hydrographic Department The Australian Joint Copying Project microfilmed a considerable quantity of the written records of the Hydrographic Department. They include letters, reports, sailing directions, remark books, extracts from logs, minute books and survey data books, mostly dating from 1779 to 1918. They can be found on reels M2318-37 and M2436-67.

  • APPENDIX O9 Salinity of Upper Spencer Gulf
    APPENDIX O9 Salinity of Upper Spencer Gulf Olympic Dam Expansion Draft Environmental Impact Statement 2009 Appendix O 135 136 Olympic Dam Expansion Draft Environmental Impact Statement 2009 Appendix O O9 SALINITY OF UPPER SPENCER GULF An understanding of the natural salinity range at Point Lowly is critical to the interpretation of the hydrodynamic modelling and ecotoxicology results, and the assessment of impacts of the proposed desalination plant. The accurate measurement of salinity is therefore critical to the assessment. O9.1 MEASUREMENT OF SALINITY O9.1.1 Introduction Absolute salinity is defined as the mass fraction of dissolved material (including gases) in seawater (Millero et al. 2008), and can be expressed in units such as parts per thousand or g/L. This dissolved material comprises mainly sodium and chloride ions (the constituents of common salt). Other major components are magnesium, calcium, potassium, sulphate and bicarbonate ions, and there are many tens of trace elements (Turekian 1968; Drever 1982). There is little variation in the composition of seawater (i.e. the ratio of the various ions) across the world’s seas or between oceanic and estuarine waters, with the variation in absolute salinity measurements being approximately 0.03 g/L (Millero et al. 2008)3. The amount of dissolved material is considered to be almost impossible to measure in practice (Millero et al. 2008). Less direct methods are therefore commonly used but results using different methods are often inconsistent. Consequently, the measurement of salinity
